AI Technical Summary

Problems solved by technology

[0004] The traditional spacecraft energy flow simulation method is relatively single, and the performance is that it can only conduct qualitative analysis on the characteristics of the satellite’s in-orbit mission and the space environment based on the parameters set in advance, lacking effective intervention of digital means, and unable to communicate with the spacecraft. Therefore, it is impossible to reflect the changes in the energy flow of the spacecraft during the full mission cycle in real time and dynamically.

[0005] In addition, the dynamic effect of traditional spacecraft energy flow simulation is relatively poor, and the simulation results can only be seen after the simulation is over. It is impossible to see the dynamic simulation data changes in real time during simulation, and it is impossible for designers to see more intuitively.
